Lol, I think they're made of inflatable balloon (just like in despicable me) - did you try poking the pyramid? LOL. Anyway, very catchy title! Wow, this pyramids are really made up of this sturdy stones huh. Great POV, this wide angled lenses comes in very handy! Nice exposure too, details are clearly seen. It seemed to be a good day then. THanks for sharing! I really need to visit this place!
